What.is.OpenJUMP?

OpenJUMP is an open source Geographic Information
System (GIS) written in the Java programming language. It is developed
and maintained by a group of volunteers from around the globe. OpenJUMP
started as JUMP GIS designed by Vivid Solutions.

What.can.OpenJUMP.do?

The current version can read and write shapefiles
simple GML files as well as several other vector formats via plugins.
It can also read from several spatial databases and write to postgis.
It has support for images and for WFS and WMS web-services.
So you can use it as GIS Data Viewer. However, its
particular strength is the editing of geometry and attribute data. One
can style the appearance of data in OpenJUMP's map display and can
export the view to SVG. A growing number of vector analysis tools for
topologic analysis and overlay operations is available too. OpenJUMP
1.8 adds coordinate reference system transforms and 1.9 adds several
spatial databases reading capabilities as well as a lot of bug fixes
and improvements. More info in our fatcs
sheet.
